A post on PlayStation.Blog by the President of Q-games Dylan Cuthbert reveals details about PixelJunk Eden's trophy and YouTube support. You will get a bronze trophy for every "seed" in a stage. Other trophies include destroying 500 "prowlers" or collecting 15 "crystal" in a single jump. Another trophy you can only achieve in 3-player mode. We also have a list of leaked trophies, from a NeoGAF post, which seems to be accurate, after the jump.
The YouTube upload feature will allow players to record gameplay and upload it directly to YouTube within the game. The procedure is simple: push one button to start and one to end. There is also no slowdown in gameplay "thanks to the power of the PS3 and its abundance of SPU processors."
Finally, they are thinking about trophies for PixelJunk Monsters as well via a patch. If they do release a patch, it will even include XMB music and "a couple of other things." We can't wait!
